I'm for libertarian free market economies.

Can you give a few examples where this has been implemented and is flourishing? I've heard much about them over the years (I was a huge Dr. Paul fan), however I haven't ever seen one in action. I seem to recall Dr. Paul was an advocate of the Austrian school. I don't put much research into economics anymore though I will admit. I studied what we have in the US with the Federal Reserve and seems like the experts all try to make it sound super complicated when it doesn't have to be.

As for decentralization, I will admit I'm a sceptic that such a thing can exist outside of a theory. People will generally covet more, and those who don't mind utilizing violence will reach for more. This will always result in the majority seeking some sort of unified centrality to combat this. Which inevitably leads to the centralized machines being co-opted by those they were designed to protect the masses from.
